NULL_VALUE

Trait Implementations

impl Clone for NullValue

fn clone(&self) -> NullValue

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NullValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NullValue

fn default() -> Self

Returns the “default value” for a type.

impl Hash for NullValue

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<NullValue> for NullValue

fn eq(&self, other: &NullValue) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ProtobufEnum for NullValue

fn value(&self) -> i32

Get enum i32 value.

fn from_i32(value: i32) -> Option<NullValue>

Try to create an enum from i32 value. Return None if value is unknown.

fn values() -> &'static [Self]

Get all enum values for enum type.

fn enum_descriptor_static() -> &'static EnumDescriptor

Get enum descriptor by type.

fn descriptor(&self) -> &'static EnumValueDescriptor

Get enum value descriptor.

fn enum_descriptor(&self) -> &'static EnumDescriptor

Get enum descriptor.

impl ProtobufValue for NullValue

fn as_ref(&self) -> ReflectValueRef<'_>

As ref

fn as_any(&self) -> &dyn Any

Convert to Any

fn is_non_zero(&self) -> bool

Is value non-zero?

fn as_ref_copy(&self) -> ReflectValueRef<'static>

Return ProtobufValueRef if self is Copy.
